consumption and greenhouse gas emissions. Glass
is the only transparent building material that helps
control the flow of heat, UV rays, and glare while
letting light into a building, increasing the overall
comfort and productivity of its occupants. The
NSG Group is committed to being at the forefront
of these developments.
Glass manufacturing excellence and innovation,
with a reputation for leading many important
technological advances in the glass industry,
including the Float process, now the world
standard for high quality glass production.
The selection of glass products has become more
complex since Pilkington invented the float glass
process in 1952. The properties of glass have
become increasingly multifaceted with the ability
to perform a wide variety of functions. The key
to these developments has been glass’s unique
attributes of transmitting daylight and mediating
the environment to provide a better place in
which to live and work.
Float Glass Manufacturing
the production of high quality glass. Float Glass
is manufactured by melting sand, soda ash,
dolomite and limestone, along with other minor
batch material, produce a continuous 12-foot
wide glass ribbon. The molten glass flows from
the furnace and “floats” over a bed of molten
tin. It is then carefully cooled to anneal the glass
– a process that minimizes the internal stresses
enabling it to be cut.
The Pilkington float glass process is renowned for
flatness and optical clarity. Our glass products are
available in clear, tinted, high performance tinted,
coated, low iron and rolled glass.
Coated Glass
oxides by the chemical vapor deposition (CVD)
process during float glass manufacturing. This
process produces extremely durable coated
products that can easily be handled, transported
and processed. These products typically combine
low emissivity, solar control, low reflection and
self-cleaning properties. Pilkington is the industry
leader in pyrolytic coating technology.

bonded to a perimeter spacer material with a
hermetically sealed airspace. The primary benefit
is insulation and solar control. Most types of glass
can be incorporated into an insulating glass unit.
Laminated Safety Glass
of glass bonded together with a plastic or resin
interlayer. If broken, the interlayer is designed to
hold the glass together. Virtually all glass types
can be laminated and the thickness and types of
interlayer can be varied to provide ballistic, bomb
or physical attack resistance. Laminated glass can
typically be cut and further processed.
Tempered Glass
than annealed glass. When broken, it shatters
into many small fragments which reduce major
injuries. This type of glass is intended for glass
facades, sliding doors, building entrances, bath
and shower enclosures, and other uses requiring
superior strength and safety properties.
Heat Strengthened
heat-treatment in which it is heated to about
680°C (1256°F) and afterwards cooled. When it
is cooled slower than tempered glass, the glass
is twice as strong as annealed glass, and the
fragments of the broken glass are larger and more
likely to remain in the frame. Heat strengthened
glass is not recognized as a “safety glass” by
typical building codes.
building design and the environment. It affects
design, appearance, thermal performance and
occupant comfort. The selection of the right glass
is a crucial component of the design process.
By identifying key issues at the design stage,
glass products can be selected to match your
specific application. NSG sales managers and
engineers are available for specific project
questions and issues at any critical design
phase as well as throughout the entire project.

products really are, you need to know a little bit
about energy and heat as it applies to glass.
l Heat gain comes from both the sun’s direct
short-wave radiation and the transfer of
energy from the exterior environment. l Solar Control is a key issue in terms of energy
savings. In hot conditions or for buildings
with high internal loads, solar control glass
is used to minimize solar heat gain by
rejecting solar radiation and help control glare.
In more temperate conditions, it can be used
to balance solar control with high levels of
natural light. l Glass can provide solar control by either
absorbing a portion of this energy (such as
tinted glass) or reflecting a portion of it
(reflective glass). In the case of
Pilkington Eclipse Advantage™ solar
control low-e, there is a combination
of the two. l In cold climates, Low-e glass will redirect
energy (room heat) back into a building, to
achieve much lower heat loss than ordinary
float glass. Different types of low-e glass allow
different amounts of free energy from the sun,
passive solar heat gain, helping to reduce
heating requirements and costs, especially in
colder months.

greater the amount of light that passes though
the glass, regardless of its color.
SHGC (solar heat gain coefficient)

radiant energy and the proportion of the absorbed

U-factor (U-value)

glass is used, then adding a lite of low-e on the
room side acts as a barrier to the absorbed heat in
the glass passing to the inside of the building.
Passive Solar Heat Gain

Thermal control low-e glazing products like
Pilkington Energy Advantage™ reduce energy
usage by allowing passive solar heat to easily pass
through the glazing. The pyrolytic low-e coating
provides thermal insulation by reducing heat loss.
That is why Pilkington Energy Advantage™ is
known as a leading passive solar glazing product
in the market.

Low-e coatings reduce the emissivity of the glass
surface. This means the glass provides greater
insulation by reflecting heat generated from
heating and other sources back inside a building.
A second line of defense is improved solar control.
Heat absorbed by the solar control glass is driven
back out by the low emissivity coating to provide
even better solar and thermal control. Low-e
